Hi guys, I just got today my new 2012 Montero GLS-V so far I am loving it. Really worth it compared to the old models, the upgrades are awesome.

Anyways, I noticed that the GLS-V doesn't have the Tire Pressure (indicator) added on the system, do you guys know how much it costs and if I do have any other alternatives that will work with the system?

Also, the back-up camera. Can other brands work with the system? I mean will it revoke the Electrical Warranty of my car?

P.S.: Mitsubishi really have hooks now on the driver's side for the floor mats. And I think they are re-doing all of their floor mats since they told me it will be coming next week pa daw.
P.S.#2: I hate the sound of the horns of the Montero (but it wasn't that bad compared to the stock horns of the 2010 Strada). Need to change it!
